Online Works

For all online works other than computer programs and databases, the registration
extends only to the copyrightable content of the work as received in the Copyright
Office and identified as the subject of the claim. The application for registration
should exclude any material that has been previously registered or published
or that is in the public domain. For published works, the registration should
be limited to the content of the work asserted to be published on the date given
on the application.

Many works transmitted online are revised or updated frequently. For individual
works, however, there is no blanket registration available to cover revisions
published on multiple dates. A revised version for each daily revision may be
registered separately, provided the revisions constitute copyrightable authorship.
A separate application filing fee would be required for each separately published
update.
